ARCOR® Spraythane

Steel surfaces are to be abrasive blasted with chloride free abrasive. Exterior applications to SSPC SP-6 Commercial gray metal finish. Immersion applications to SSPC SP-5 White metal. Grind flat all burrs, weld seams, radius sharp edges. Fresh blasted steel surfaces can be self-primed or use ARCOR™ S-30 Prime for corrosive undercutting protection in salt water service.

Concrete surfaces should be degreased if oil and grease contamination is present. Degreased surface shall be high pressure washed, acid etched and high pressure washed again so surface is clean and free of all grease and oils and surface laitance. Existing coatings should be abrasive blasted to clean concrete. Self-Prime or, if extensive pinholes prime with ARCOR™ EE-10 or EE-70
